Imago Relationship Therapy is a form of couple's therapy developed by Harville Hendrix, Ph.D., author the the best selling book Getting the Love You Want: A Guide for Couple's.
It's basic premises are as follows:

We were born whole and
complete

We became wounded between birth and early adulthood by our primary
caretakers (usually unintentionally). These wounds can result in fears of abandonment or being controlled, for
example

We have a composite picture of all the positive and negative traits of our primary caretakers deep in our unconscious mind. This is called our Imago. We are attracted
to a person who fits our Imago

The first two relationship stages, "Romantic Love" and the "Power Struggle," are
engaged in at an unconscious level. Our unconscious mind chooses our partner for the purpose of healing childhood
wounds

Romantic Love is the door to commitment and/or a way of connecting us with a partner who can help us heal and become whole, if they are willing and we let
them

We move into the Power Struggle as we deepen our commitment to this person. The Power Struggle is a normal part of all relationships. It also provides the opportunity for individual growth and healing. It is the time when we take off the rose colored glasses and see our partner's faults or limitations. Sometimes we see faults that are not really there, but are projections of what others have done to us in the
past

The goal of Imago Relationship Therapy is to help couples move out of the power struggle and into conscious, intimate, committed
relationships

This is accomplished by teaching couples techniques that enhance emotional safety and encourage each partner to speak their truth to each
other
